Abstract

La présente invention concerne un radar de cartographie et plus particulièrement un radar de cartographie pour hélicoptère. Le radar comporte un aérien animé d'un mouvement de rotation circulaire, disposé de préférence à l'extrémité libre d'une des pales de l'hélicoptère, des moyens d'émission-réception couplés à l'aérien, des moyens de démodulation des signaux de réception et des moyens de corrélation des signaux démodulés par un signal synthétique obtenu par modulation de phase d'un signal d'amplitude constante selon le mouvement de rotation de l'aérien. Applications à la détection d'objets fixes ou mobiles.The present invention relates to a mapping radar and more particularly to a mapping radar for a helicopter. The radar comprises an aerial driven by a circular rotational movement, preferably arranged at the free end of one of the blades of the helicopter, transmission-reception means coupled to the aerial, demodulation means reception signals and means for correlating signals demodulated by a synthetic signal obtained by phase modulation of a signal of constant amplitude according to the rotational movement of the aircraft. Applications to the detection of fixed or moving objects.
